Based on previous work, add a new driver for the v2 usb peripheral found on
stm32f0 and l0 devices.
Correspondingly, add a usb gadget zero test suite for the f0. L0 device level
code isn't yet ready, but will add the test case when it moves in.
Work by Frantisek Burian, Kuldeep
Singh Dhaka, Robin Kreis, fenugrec and zyp on irc, and all those forgotten.
The breaking changes here changes in header location, and changes in driver
name passed down to the usb stack.
Changes affect: stm32f102/f103, stm32l1, and some f3 parts
* instead of the confusingly generic "usb" use the name "st_usbfs" for the USB
Full speed peripheral ST provides in a variety of their stm32 products.
Include directives should change as:
#include <libopencm3/stm32/usb.h> => <libopencm3/stm32/st_usbfs.h>
* instead of the confusingly specific "f103" name for the driver, use
"st_usbfs_v1" [BREAKING_CHANGE]
Instead of:
usbd_init(&stm32f103_usb_driver, .....) ==>
usbd_init(&st_usbfs_v1_usb_driver, .....) ==>
The purpose of these changes is to reduce some confusion around naming, but
primarily to prepare for the "v2" peripheral available on stm32f0/l0 and some
f3 devices.
